A very useful camera bag tool......for all you budding wannabe professional landscape photographers (& professionals alike) out there who like to catch the sunrise/sunset for great photo's.FREE download on PC/Mac.

The Photographer's Ephemeris (TPE) is a tool to help with the planning of all types of outdoor photography, but particularly landscape and urban scenes.

It is a map-centric sun and moon calculator: see how the light will fall on the land.

TPE's map-based approach means you are not limited to a predefined list of locations, which often don't include the places many photographers go. Instead, search for any place name on the planet or position the map pin exactly where you want it.

Advanced features including automatic time zone and elevation detection, correction for atmospheric refraction and height above the horizon, ensuring that you have the best possible information for planning your shoot.

You can even determine when the sun or moon will be visible behind nearby hills and mountains.
